I've been lurking on these boards for about a month now and finally decided to join. I was utterly impressed by the support from the entire community and would first like to thank everyone within the community for helping me get my hardware up and running, (from CPU, to GPU, and now finally ASICs!) even though we may have never directly spoken.
That being said though I'd love to get a little bit more information about overvolting. I've seen some threads where everyone discusses overclocking, and even a couple of threads where some upper limits on overvoltage are discussed but it was fairly minimal. I've set my clock frequency on both of my Antminers to about 237, because that seems to be where they are most stable. One miner averages roundabouts 500GH/s and the other runs about 40-60Gh/s slower than that at the same clock frequency for some odd reason. What I was wondering though is whether or not I should overvolt the machine to help that along, or has Bitmain set up the controller to automatically adjust voltage to match desired clock speed? I've been struggling to find these things out.
If you need some specific information:
2 Antminer S3+ (I bought these seconhand so I'm not sure the batch number)
2 EVGA 500W 80 Plus PSU with splitters to supply each rail (yes, I know probably not the best choice, but since the miners were second hand I wanted to make sure they worked before buying Gold PSUs)
According to the miner interfaces, the chips on each board are all working properly at 237M. If i got above that, I'll usually have at least one chip fault out on a board.
It may not matter, but if for some odd reason it does, I disabled the WiFi interfaces on each machine and run Ethernet cables to both. I did this because one of the WiFi adapters was being fussy and after accidentally deleting the Wifi interface and having to reset the machine to factory, I decided to keep a physical connection. Sometimes wires are just more simple
